What are the types of AC voltage stabilized power supplies?
Regarding the models and types of regulated power supplies, they can generally be divided into four categories. DC, AC, inverter and switching regulated power supplies. For these four categories of different types of regulated power supplies. Although their working methods and principles are somewhat the same, but the same also has a lot of differences. The following three sections for these four different types and types of voltage stabilized power supply for a detailed introduction.
The first category is AC regulated power supply, AC is divided into single-phase and three-phase regulated power supply, can also be divided into contact and non-contact regulated power supply. In practical application, it can be summarized as the following classifications of commonly used AC regulated power supplies:
① ferromagnetic resonant AC voltage regulator. Composed of saturated choke and the corresponding capacitor, with constant voltage volt-ampere characteristics.
② magnetic amplifier type AC voltage regulator. Magnetic amplifier and autotransformer in series, the use of electronic circuits to change the impedance of the magnetic amplifier to stabilize the output voltage.
③Sliding type AC voltage regulator. Stabilize the output voltage by changing the position of the sliding contact of the transformer.
Inductive AC voltage regulator. By changing the phase difference between the secondary and primary voltages of the transformer, the output AC voltage is stabilized.
⑤ Thyristor AC voltage regulator. The thyristor is used as the power adjustment element. High stability, fast response and no noise. However, it causes interference to communication equipment and electronic equipment.After 1980s, three new types of AC voltage stabilized power supply appeared: compensated AC voltage stabilizer. Numerical control type and stepping type AC voltage regulator. Purification type AC voltage regulator. Has a good isolation effect, can eliminate the spike interference from the power grid.
The second major category is DC voltage stabilized power supply:
Also known as DC voltage regulator. Most of its supply voltage is AC voltage, when the voltage of the AC supply voltage or output load resistance changes, the direct output voltage of the regulator can remain stable. The parameters of the regulator are voltage stability, ripple factor and response speed.
The third category is inverter voltage stabilized power supply
The so-called inverter regulated power supply is also called frequency conversion power supply, this inverter power supply using 16-bit Motorola processor control, high-frequency PWM design, the original imported Mitsubishi 1GBT drive. Efficiency of more than 85%. Fast response, for 100% de-loading/loading, the response time of voltage stabilization is within 2ms. The frequency conversion power supply overload capacity, instantaneous current can withstand 300% of the rated current. Pure waveform, high and stable frequency, no interference magnetic wave (EMI, EMC). Frequency conversion power supply is not only the best power supply for R&D and laboratory, measurement room, but also the standard power supply for EM/EMC/safety testing.
The fourth category is switching regulated power supply
The schematic and equivalent block diagram of a switching regulated power supply, which is composed of a full-wave rectifier, switching tube V, excitation signal, current-continuing diode Vp, energy-storage inductor, and filter capacitor C. In fact, the core part of the switching regulated power supply is a DC transformer.
There is another kind of CNC regulated power supply:
CNC stabilized power supply: it is through the observation area in the output of the equipment sampling, the present voltage with the rated voltage to make a comparison, check, such as the comparison is negative, then send data to the central processing unit (CPU), the central processor to make the command of the voltage plus. At the same time, the detection area detects whether the semiconductor has been turned on and off. After confirming that there is no error, the central processor makes a voltage plus command to control the semiconductor to work so as to reach the standard of rated voltage. If the value is positive, the central processor makes the command of voltage decreasing, and the whole process is digitized in only 0.048 seconds.
